This article examines some of the performance outcomes from a practised-based research project that took place with adolescent girls attending an after-school drama club. Participants experimented with slapstick humour in a series of workshops, before presenting their own devised physical comedy performance for a live audience. Comic performances are explored in relation to the opposition between comedy and what is coded as appropriate feminine behaviour, and those current regimes of gender that encourage girls to discipline and control the body in pursuit of a feminine ideal. Through detailed analysis of girls' practical endeavours, and by privileging their personal observations and reflections on working in the style, I argue that slapstick enabled girls to make unruly experiments with the body that allowed normative conceptions of gender to be temporally undone. However, I also reflect on how this emancipatory process was troubled when girls watched recordings of the work and became spectators to their own transgression.
